TGRTC Supervisor Exam 2026: Syllabus, Exam Pattern & Preparation Plan

Introduction

This guide explains the TGRTC Supervisor exam syllabus, pattern, marking scheme and a week-wise preparation strategy for both Traffic (TST) and Mechanical (MST) candidates. 

I know exactly how it feels when a major notification like the TGRTC Supervisor Trainee comes out. There is excitement, but there is also a lot of confusion. "Where do I start?" "Is the syllabus too hard?" "Can I really beat the competition?"

I started Edunaukri 360 to answer these exact questions. With 198 vacancies (84 for Traffic and 114 for Mechanical) and the exam date set for March 29, 2026, the clock is already ticking. I don’t want you to just "try" for this exam; I want you to dominate it.

In this guide, I’m breaking down everything—from the 200-mark syllabus to the exact strategy I would use if I were preparing alongside you today.

1. Understanding the 200-Mark Challenge

I always tell my students, "Know your enemy before you go to war." The TGRTC exam is a single-paper OMR test with 200 questions. You have 3 hours (180 minutes), which means you have less than one minute per question.

The Marking Structure (For both TST and MST)

Subject

Marks

Why it matters

Supervisory Aptitude

60

The Kingmaker. This is where the job is won or lost.

Reasoning

40

High scoring if you know the tricks.

Technical/Numerical

40

Numerical for TST; Engineering for MST.

General English

30

Simple grammar and comprehension.

General Knowledge

30

Current affairs and basic science/history.


2. My "Deep Dive" into Supervisory Aptitude (60 Marks)

I cannot stress this enough—you must master this section. Most candidates will do okay in Math or GK, but many will fail here because it’s a new subject for them.

When I look at the syllabus, I see that it's not just about "common sense." As per my knowledge You need to understand:

  • Traffic Rules & MV Act: Questions on Section 112 (Speed Limits) and Section 119 (Signals). You need to know these by heart.
  • Basic Management: Think like a boss. How do you handle a driver who is late? How do you manage a bus schedule during a festival?
  • Problem Solving: You might get "What would you do?" scenarios.
3. The Difference Between TST and MST

I’ve had candidates ask me if they can study the same thing for both. The answer is No.

  • For Traffic Supervisor (TST): Your 40-mark section is Numerical Aptitude. I suggest you focus on ratios, Percentages, and Time & Distance. Since it's a transport job, expect questions related to speed and fuel!
  • For Mechanical Supervisor (MST): Your 40-mark section is Engineering Aptitude. This is where your Diploma in Automobile or Mechanical Engineering comes in. I want you to go back to the basics of IC Engines and Workshop Technology.

4. Your Day-by-Day Study Plan

If you start Right Now, you have roughly 8 weeks. Here is the schedule I recommend:

Phase 1: The Foundation (Weeks 1-3)

During these weeks, I want you to finish the "Heavy" subjects. Spend 4 hours a day on Supervisory Aptitude and Numerical/Engineering Aptitude. Don't worry about speed yet; just make sure you understand how to solve the problems.

Phase 2: The Speed Phase (Weeks 4-6)

Now, we bring in Reasoning and English. Start using a timer. I believe that practising with a stopwatch is the only way to beat the 180-minute limit.

Phase 3: The Revision & Mock Phase (Weeks 7-8)

In the final 15 days, I don't want you to learn anything new. Just solve one Mock Paper every single morning at 10 AM (the actual exam time). This trains your brain to be at its sharpest when it matters most.

5. My Personal Advice for All Candidates

I know many of you are coming from a technical background and might find General English or GK boring. My advice? Don't ignore them.

Even a 5-mark difference in these "smaller" sections can be the reason you get the job over someone else. Spend just 30 minutes an evening reading the last 6 months of Telangana current affairs. I think you may expect at least 10–15 questions just on these 'Decision Making' situations.

Conclusion: You Can Do This!

I’ll be honest—competition in Telangana is tough. But remember, the exam is in Telugu, English, and Urdu. This is a huge advantage for you!

My final word to you: Don't wait for a "better time" to start. Open your books today. Whether it’s mastering a topic or learning the Motor Vehicles Act, every hour you put in now is an investment in your future.

I want to leave you with one last thought. I’ve seen many candidates wait for the 'perfect' Monday or the 'perfect' time after a festival to start studying. But I’ll be honest with you—that perfect time never comes. Life will always be busy. The difference between those who get the TGRTC uniform and those who don't is simply who started today.

Every single hour you put in while others are resting is an investment in your own future. You are not just studying; you are building a life where you have a secure government salary and a respected position in society.

Take it one day at a time, one topic at a time. Stay focused on your goal, work hard even when no one is watching, and keep your head held high.

Workshop Safety Rules for ITI Students (Lathe, Welding & Machine Shop Guide)

 Industrial Training Institutes (ITIs) play a vital role in developing skilled manpower for industries such as manufacturing, electrical, mechanical, construction, automobile, welding, and CNC operations. ITI students work daily with machines, tools, electrical equipment, chemicals, sharp instruments, and heavy materials. Due to this, the risk of accidents, injuries, and hazards is always present. Therefore, safety is not an option – it is a necessity.

Safety rules are designed to protect students from physical harm, health hazards, and life-threatening accidents. Following safety rules not only saves lives but also builds discipline, responsibility, professionalism, and a good work culture. A safe trainee becomes a safe worker, and a safe worker becomes a responsible professional.

In my 12 years of experience teaching in various mechanical engineering institutions and working on industrial shop floors, I have seen one truth remain constant: Technical skill is worthless if you are not safe. Industrial Training Institutes (ITIs) are the backbone of India’s manufacturing sector. Whether you are learning Welding, Electrician trades, or advanced CNC Machining, you are working with forces that can be unforgiving. A single moment of overconfidence can lead to a life-altering accident.

In this guide, I am moving beyond the standard textbook rules. I am sharing the practical safety protocols that I have strictly enforced in my workshops to ensure every student goes home as healthy as they arrived.

Importance of Safety in ITI Training

Safety in ITI training is important for many reasons:

  1. Prevention of accidents – Most industrial accidents occur due to carelessness, lack of knowledge, and unsafe practices.
  2. Protection of life and health – Safety rules protect students from burns, electric shocks, cuts, fractures, and permanent disabilities.
  3. Development of discipline – Safety teaches discipline, responsibility, and self-control.
  4. Professional behaviour – Industries expect trained workers to follow safety standards strictly.
  5. Legal responsibility – Institutions and industries are legally responsible for student safety.
  6. Confidence in work – A safe environment creates confidence and focus in learning.

Hence, safety education is as important as technical education in ITI training

1. Personal Safety Rules

Personal safety is the foundation of workshop safety. Every ITI student must take responsibility for their own protection.

  • Students must always wear Personal Protective Equipment (PPE) such as safety shoes, gloves, a helmet, goggles, an apron, and a mask according to the type of work.
  • Loose clothes should not be worn because they can get caught in machines.
  • Long hair must be tied properly to avoid entanglement in rotating parts.
  • Jewellery such as rings, chains, bracelets, and watches must be removed before practical work.
  • Students should maintain personal hygiene and cleanliness.
  • Proper posture must be followed while standing, sitting, lifting, and working.
  • Never work when feeling tired, sick, or mentally disturbed.
    Equipment Purpose
    Safety Goggles Protect eyes from chips & sparks
    Gloves Prevent cuts and burns
    Safety Shoes Protect feet from heavy objects
    Apron Protect your body from hot chips

Personal safety begins with self-discipline and awareness.

2. Workshop Safety Rules

The workshop is a high-risk area where machines, tools, and materials are constantly in use.

  • The workshop should always be clean and well-organised.
  • Oil spills, water, and waste materials must be cleaned immediately.
  • Tools should be kept in their proper places after use.
  • Running, shouting, playing, or joking inside the workshop is strictly prohibited.
  • Only trained students should operate machines.
  • No unauthorised entry into machine areas.
  • Always follow the instructions given by the instructor.
  • Never distract others while they are working on machines.

A clean and disciplined workshop reduces accidents and improves productivity.

3. Machine Safety Rules

Machines are powerful and dangerous if not handled properly.

  • Always inspect machines before starting work.
  • Check guards, belts, switches, and safety devices.
  • Never remove machine guards.
  • Do not operate machines with damaged parts.
  • Switch off the machine before adjusting, cleaning, or repairing.
  • Do not touch moving parts.
  • Use correct speed, feed, and tools for machining operations.
  • Stand in a safe position while operating machines.
  • Never overload machines.

Machine safety is based on correct operation, awareness, and responsibility.

The Gold Standard: Applying 5S in the ITI Workshop

In top-tier industries such as Tata Motors and Maruti Suzuki, safety is managed through the 5S Methodology. As an engineer, I believe every ITI student should learn this early.

  1. Sort: Remove all unnecessary tools from your workbench. Only keep what you need for the current job.

  2. Set in Order: "A place for everything and everything in its place." Your spanners and measuring tools should be arranged so you can find them even in the dark.

  3. Shine: Clean your machine after every shift. Cleaning is inspection; while cleaning, you might notice a loose bolt or an oil leak that could cause an accident later.

  4. Standardise: Create a checklist. Every student should follow the same safety steps every single day.

  5. Sustain: Make safety a habit. It is the hardest "S" but the most important for a long career.

4. Electrical Safety Rules

Electrical hazards can cause serious injuries and death.

  • Never touch electrical equipment with wet hands.
  • Use insulated tools and safety gloves.
  • Do not use damaged wires, plugs, or switches.
  • Always switch off the power supply before repair work.
  • Do not overload sockets.
  • Earthing must be properly maintained.
  • Report electrical faults immediately.
  • Avoid temporary wiring and loose connections.

Electrical safety saves lives and prevents fires.

5. Fire Safety Rules

Fire accidents can cause large-scale damage and loss of life.

  • Students must know the location of fire extinguishers and emergency exits.
  • Smoking is strictly prohibited in workshops.
  • Flammable materials must be stored safely.
  • Do not keep inflammable liquids near heat sources.
  • Learn the correct use of fire extinguishers.
  • In case of fire, inform the instructor immediately.
  • Follow emergency evacuation procedures calmly.
  • Do not panic during emergencies.

Fire safety awareness is essential in every training institute.

6. Tool Safety Rules

Tools can be dangerous if used incorrectly.

  • Use tools only for their intended purpose.
  • Do not use damaged or broken tools.
  • Sharp tools must be handled carefully.
  • Tools should not be thrown or misused.
  • Always return tools to their proper place after use.
  • Carry tools safely, not in pockets.
  • Use correct tools for each job.

Proper tool handling prevents injuries and improves work quality.

7. Material Handling Safety

Handling heavy and sharp materials requires care.

  • Use proper lifting techniques.
  • Do not lift heavy loads alone.
  • Use trolleys, cranes, or helpers.
  • Store materials properly.
  • Do not keep materials on walkways.
  • Sharp materials should be covered and labelled.
  • Wear gloves while handling rough or hot materials.

Correct material handling prevents muscle injuries and accidents.

8. Chemical Safety Rules

Some ITI trades use chemicals such as oils, solvents, gases, and cleaning agents.

  • Read safety labels carefully.
  • Use gloves and masks while handling chemicals.
  • Do not smell or taste chemicals.
  • Store chemicals in labelled containers.
  • Avoid mixing chemicals without permission.
  • Wash hands after chemical handling.
  • In case of chemical contact, inform the instructor immediately.

Chemical safety protects health and prevents long-term diseases.

9. First Aid and Emergency Safety

Preparedness saves lives during emergencies.

  • Students must know the location of the first aid box.
  • Minor injuries should not be ignored.
  • Serious injuries must be reported immediately.
  • Emergency contact numbers should be displayed.
  • Students must know emergency exit routes.
  • Follow emergency drills properly.
  • Help injured persons safely.

Quick action during emergencies reduces damage and saves lives.

10. Psychological and Behavioural Safety

Safety is not only physical but also mental and behavioural.

  • Avoid stress and fatigue.
  • Do not work in anger or emotional disturbance.
  • Respect instructors and fellow students.
  • Maintain discipline and teamwork.
  • Avoid risky behaviour and overconfidence.
  • Develop a safety mindset.

A calm and focused mind ensures safe work.

Role of ITI Students in Safety Culture

Every ITI student is responsible for safety, not only for themselves but also for others. Safety culture is built by:

  • Awareness
  • Discipline
  • Responsibility
  • Training
  • Practice
  • Respect for rules

Safety should become a habit, not a rule.

Conclusion

Safety is Your Real Degree

At the end of your two-year ITI course, you will receive a certificate. But your real success is completing that course without a single injury. In my 12 years of teaching, I have noticed that the most successful technicians aren't always the fastest—they are the ones who work the smartest and safest.

Remember: "Safety is not a gadget, but a state of mind." Use the tools, follow the 5S rules, and respect the machines. Your family is waiting for you to come home safe after your shift. Therefore, safety is a responsibility, habit, discipline, and way of life.

Workshop Safety Viva Questions for ITI Students

1. Why are loose clothes dangerous in a workshop?
Loose clothes can get caught in rotating machine parts like the lathe chuck or drill spindle, causing serious injury.

2. Why should chips not be removed by hand?
Metal chips are sharp and hot. They can cut skin or cause burns. A brush or chip hook must be used instead.

3. Why is coolant used during machining?
Coolant reduces heat, improves tool life, and gives a better surface finish to the job.

4. Why should we wear safety goggles?
To protect eyes from flying metal particles, sparks and dust produced during cutting operations.

5. Why must the machine be stopped before measuring the job?
Measuring while rotating can pull the measuring instrument or hand into the machine.

6. What is the purpose of safety shoes in a workshop?
They protect feet from falling heavy workpieces and sharp metal pieces on the floor.

7. Why should tools be kept at proper place after use?
Improperly kept tools cause accidents and damage cutting edges.

8. Why is cleaning with compressed air dangerous?
Air pressure can throw metal particles into the eyes and skin.

9. Why must long hair be covered while operating machines?
Hair can get entangled in rotating parts and cause severe injury.

10. What should be checked before starting a machine?
Workpiece clamping, tool tightening, speed selection, guards and coolant supply must be verified.

CNC Programming Format Explained with Example (Fanuc Beginner Guide)

Introduction

A CNC program is a set of instructions written in G-code and M-code that tells a CNC machine what to do, how to do it, and in what order to do it. Every CNC program follows a fixed structure so that the machine can read and execute it correctly without errors. If the program is not written properly, then it ends up with an accident. That means the turret might hit the chuck.

 The CNC program is written in a fixed format called program blocks, which include a safety block, work offset (G54), tool call, spindle command, cutting moves, and program end.

CNC programming is used in different types of CNC machines, such as lathes and milling machines.

The following are the parts of the program structure.

1. Program Number (Program Identification)

Every CNC program starts with a program number, which helps the machine and operator identify the program.

Example:

O0001

  • O means program
  • 0001 is the program number
  • Each program must have a unique number

2. Safety Block (Initial Setup Block)

The safety block prepares the machine for safe operation and avoids accidental movement.

Example:

G21 G17 G90 G40 G49 G80

Explanation:

  • G21 – Metric system (mm)
  • G17 – XY plane selection
  • G90 – Absolute programming
  • G40 – Cancel cutter radius compensation
  • G49 – Cancel tool length compensation
  • G80 – Cancel canned cycles

 This block ensures the machine starts in a known and safe condition.

3. Work Coordinate System Selection

This tells the machine where the job zero is located.

Example:

G54

  • G54 to G59 are work offsets
  • Helps in accurate machining

4. Tool Selection and Tool Change

The machine is instructed to select and change the required tool. The turret rotates and points out the required tool towards the workpiece in the chuck.

Example:

T01 M06

  • T01 – Tool number 1
  • M06 – Tool change command

5. Spindle Speed and Direction 

This block controls the rotation of the spindle.

Example:

S1200 M03

  • S1200 – Spindle speed (RPM)
  • M03 – Spindle ON clockwise
  • M04 – Counter-clockwise
  • M05 – Spindle stop

6. Feed Rate Command

Feed rate defines how fast the tool moves while cutting.

Example:

F150

  • F150 – Feed rate in mm/min
  • Correct feed rate ensures good surface finish and tool life

7. Rapid Positioning (Non-Cutting Movement)

Used to move the tool quickly without cutting.

Example:

G00 X0 Y0 Z5

  • The tool moves fast to the specified position
  • Used for approach and retract

8. Cutting Movement (Linear Interpolation)

Actual cutting is done using linear movement.

Example:

G01 X50 Y0 Z-2 F150

  • G01 – Linear cutting movement
  • Tool moves at feed rate
  • Used for straight cuts

9. Circular Interpolation (Arc Cutting)

Used for machining circles and arcs.

Example:

G02 X40 Y40 I20 J0

  • G02 – Clockwise arc
  • G03 – Counter-clockwise arc
  • I and J define arc centre

10. Coolant Control

Coolant helps in cooling the tool and removing chips.

Example:

M08

  • M08 – Coolant ON
  • M09 – Coolant OFF

11. Program Repetition

Used when the same machining operation is repeated.

Example:

M98 P0100

  • Calls subprogram
  • Saves programming time

12. Tool Retraction and Spindle Stop

After machining, the tool is safely moved away.

Example:

G00 Z50

M05

  • Tool moves up
  • Spindle stops

13. Program End and Reset

Marks the end of the CNC program.

Example:

M30

  • Ends the program
  • Resets for next cycle

Conclusion:

I always say that a clean CNC program makes your work much easier and safer. When I write a program step-by-step, the machine works perfectly, and the parts come out exactly right. I want to help you understand these steps so you can quickly find mistakes. A good program is the best way to save time and do high-quality work.
